I say this as someone who knocked an opposing fan out during a UA game while I was in college and was involved in a brawl at a professional game that I won't mention during 2003:
This kind of stuff is really immature and does nothing but ruin the game for the people who sit around the area of the scene (particularly families and older people). This girl, who is not that hot in my opinion, should be ashamed of herself and the big guy showed some serious stones by backing off
P.S. The Lions fans that I have met over the years have been some of the coolest fans of all (Along with Bengal fans). I kind of feel a bond with them knowing that we are not frontrunners and are actual football fans rather than casual observers
